Im trying to brush up on my math skills before i start college since ive been out of hs for 2 years now and i cannot for the life of me remember how to simplify a one part factorial.. im dealing with

5!

7!

9!

in my head i thought i should just multiply it out like

5! = 5 * 4 * 3 * 2 * 1 = 120 etc.. but is that simplifying it?

Hey there!


5!

= 5(4)(3)(2)(1)

= 20(3)(2)(1)

= 60(2)(1)

= 120(1)

= 120


Therefore, your answer should be: 120

7!

= 7(6)(5)(4)(3)(2)(1)

= 42(5)(4)(3)(2)(1)

= 210(4)(3)(2)(1)

= 840(3)(2)(1)

= 2,520(2)(1)

= 5,040(1)

= 5,040
Therefore, your answer should be: 5,040

9!
= 9(8)(7)(6)(5)(4)(3)(2)(1)

= 72(7)(6)(5)(4)(3)(2)(1)

= 504(6)(5)(4)(3)(2)(1)

= 3,024(5)(4)(3)(2)(1)

= 15,120(4)(3)(2)(1)

= 60,480(3)(2)(1)

= 181,440(2)(1)

= 362,880(1)

= 362,880

Therefore, your answer should be: 362,880


Good luck on your assignment & enjoy your day!
